What are the distinguishing characteristics of a mineral fracture and how does it impact the overall structure and composition of the mineral?

Mineral fracture refers to the way a mineral breaks when subjected to external forces. There are two main types of fractures: cleavage and fracture. Cleavage results in smooth, flat surfaces, while fracture results in rough, irregular surfaces. The type of fracture can impact the overall structure and composition of the mineral by affecting its strength, durability, and appearance. Minerals with cleavage tend to break along specific planes of weakness, while minerals with fracture may break in unpredictable ways, impacting their physical properties and usability.
